Worldflight 2019

Donations Starting Early

With 50 Days Left, it's time to start Counting Down to Worldflight 2019. Beginning in August, we had 2 kind gentleman lead the way on our quest for donations to this amazing Charity Event. Over the Past 6 Years, we (This community) Has helped to raise over $25,000.00USD to help the kids and their families of the All Children's Hospital in St. Petersburgh, Florida. Kicking off the donations this year these Two Hero's are leading the way to another Successful Year. I personally want to thank these two Gentleman and use this opportunity to have all of you donate to our wonderful cause.

Thank you in advance for your help and please wish us much success for our 2019 event.

I looked for that pcb material but i didnt know the name for it. Wish now that i had seen it earlier... I will try to implement next module with both the pcb and the wires you linked. It will also be easier since the mcp is so wide, other modules will hopefully be smaller size.

Finally my mcp is coming to an end! Thanks to the forum i switched to usw awg22 cables and that + serialconnect all the grounds was the final solution. Everything is in place, just nedd to hook up the microcontroller and make led extensions to the max7219 drivers.

I ordered the mcp and afis casings + the efis panels from simworld today!

Pheeew. Lots of new stuff. Every single button and switch is now mapped and the last thing to do is the backlight multiplexing including the leds for the button titles.

One really negative thing with this mcp is that its more challeging to solder and fit tight components than actually hook it up. I hope this will be the most tightspace module on the 737, otherwise i probobly will give the hobby up...

Well enough of that, my leds are installed but it resulted in a strange problem with that the last daisy chained max7219 is loosing power and is unreliable.If i skip the first three max7219 the last one shines strong and reliable so i think it is a power/daisy chain problem.

It turns out when, manually booting, the Teensy is really fast so the instanciating of the LedControl is "sortof" working. But if i put a deplay for like 1 sec and then reassign them afterwards then the MAX7219 works stable with all the serial connections. (now 6 of them)

After gaining some experience in building an MCP, i removed all the wires and started from scratch!!!

What i didnt like with my old setup and how i am improving it.

Wire mess: wires right to left, now i will use two teensy, one for right cables and one for left cables. That way it will be more clear of space.

cable thickness: i used too thick cables, multithreads cables, very hard to solder and thick cables makes it tought to get some space to see anything after a while with lots of cables. Now i use superthing singlethread cable which is sooooo easy to solder!

ground: i used to go component by component. But this way it is much harder to find ground errors, bad solderings or a broken cable.Now i wire all components with its own ground cable and then use a PCB Board to connect them, it will still only be one ground cable to the teensy board.

Max7219 cables: a mess with hardsoldered wires. Now i use a connector, that way i can remove the cables if i need to search for other errors or resolder other things. without being able to remove these cables i cannot do anything without burning the cables with the solder-tool.

Finally, i will order white Leds from Ebay. If the Simworld panel is that great, i really need to have the white leds like in the real MCP.

When i use the smaller cables, it will be easier also to attach the LED-strip that will work as backlight.

Some picture to show my mess. =)

My EFIS Panels are in the works aswell. Will post new update when i have installed the 3mm Leds.
